How does a brain aneurysm affect the body?

Greenville Health System
How an aneurysm affects the body depends on its nature. Aneurysms that are small or not growing generally produce no symptoms and may never cause any adverse impacts to the body. Aneurysms that are growing may put pressure on brain tissue or surrounding nerves in the brain. This may result in pain behind or above the eyes, dilated pupils, a drooping eyelid, changes in vision, numbness, or even face paralysis.

Double vision, neck stiffness, light sensitivity and confusion also are possible symptoms.
